When you make the circle bigger or smaller which number of the standard equation for a circle centered at the origin changes?

Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9


What shapes contains a circle?

another, larger circle, perhaps. or a larger shape than the circle.


How do you find the gap of one cirlcle in a larger circle?

Find the area of both circles (A = πr2) and subtract the area of the larger circle from that of the smaller circle inside it.


What A circle with a radius of 3 cm shares a center with another circle that has a radius of 5 cm. Find the probability that a randomly selected point is in the larger circle but not in the smaller ci?

We can look at total areas (and ignore units-they're all the same). The smaller circle has an area of 9pi, and the larger circle has an area of 25pi. The smaller circle is entirely inside of the larger circle. So anything not in the smaller circle is in the larger circle. 16pi square centimeters are part of only the larger circle. 16pi/25pi=.64. So the desired probability is .64.


What is the reason for pi?

In Geometry, pi lets us determine a circle's circumference if we know the circle's diameter (or radius, which is half the circle's diameter). We can determine this because the circumference is always pi (~3.14) times larger than the diameter of the circle. So, if the diameter of a circle is 1 foot, we know the circumference is 1 ft x pi which is approximately 3.14 feet. The formula for circumference is C = 2 x pi x r. Multiplying the 2 and the r (radius) in that equation gives you the length of the diameter of the circle, so the equation can be rewritten as C = pi x d which is what I used in the example in the last paragraph. Pi is also used to find the area of a circle by using the equation A=pi x r2. Calculus was used to create that formula which is beyond the scope of this explanation.

Which number in the standard equation for a circle centered at the origin should one increase to make the circle larger?

x2 + y2 = r2, the equation of a circle centered at the origin. If you want to make the circle larger, increase the radius length.

What does pi actually represent?

Generally, Pi is used to represent the rate of change of the circumference of a circle as it's diameter increases. This can be shown using the equation [circumference = Pi * diameter], that is the circumference of a circle is always Pi times larger than it's diameter.


How do circular folds increase the surface area for digestion and absorption in the intestine?

Folds increase the surface area to volume ratio.Imagine a circle with folds all around the edge and another circle the same size with a flat edge. Both circles have the same volume, but the one with the folds has a much larger surface area.

What is a circle with a little circle in it called?

An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
